The present embodiment provides a multifunctional helmet, as shown in fig. 1 and 2, which includes a helmet body 100, a pneumatic device 200, and a first air guide duct 300; a goggle lens 110 is arranged on the front side of the helmet body 100, and the goggle lens 110 is rotatably connected with the helmet body 100; the goggle lens 110 is used for blocking outside wind or rain for a user when the user wears the multifunctional helmet; the goggle lens 110 is a common component on a helmet, and the detailed structure thereof is not described again in this embodiment; the pneumatic device 200 is disposed on the helmet body 100 and detachably connected to the helmet body 100, one end of the first air duct 300 is connected to the pneumatic device 200, and the other end of the first air duct is fixed above the goggle lens 110, and the first air duct 300 can be disposed in the shell of the helmet body 100 to ensure the aesthetic appearance of the multifunctional helmet; the pneumatic device 200 comprises an air pump and a heating element, so that when the air pump pumps high-pressure air flow, the air flow is heated by the heating element, high-pressure hot air flow is generated by the pneumatic device 200, and the generated high-pressure hot air flow is sprayed to the outer wall of the goggle lens 110 through the first air guide pipeline 300, so that rainwater is prevented from attaching to the goggle lens 110 to obstruct the sight of a driver. Further, since the high-pressure airflow jetted to the outer wall of the goggle lens 110 is hot, the temperature difference between the inside and outside temperatures of the goggle lens 110 is small in cold weather, thereby preventing the interference of the aerosol generated by the inner wall of the goggle lens 110 to the sight of the driver.

Meanwhile, in rainy days, the temperature is usually low, or in other situations where no rainwater exists but the temperature is low, the inner wall of the goggle lens 110 is also easily fogged due to the difference between the internal temperature and the external temperature, and after the pneumatic device 200 sprays high-pressure hot air on the outer wall of the goggle lens 110 through the first air guide pipeline 300, the difference between the internal temperature and the external temperature of the goggle lens 110 is greatly reduced, so that the interference of the driver's sight line caused by the generation of aerial fog on the inner wall of the goggle lens 110 is avoided.

According to the invention, the pneumatic device sprays high-pressure hot air on the outer wall of the goggle lens 110 through the first air guide pipeline 300, so that rainwater cannot be attached to the outer wall of the goggle lens 110, fog generated on the inner wall of the goggle lens 110 due to overlarge temperature difference between the inside and the outside is avoided, and the influence on the sight of a driver in rainy days or at low temperature is avoided.
